Chapter 35 Configuring IP Unicast Routing
Configuring IP Addressing
Configuring routing consists of several main procedures:
• To support VLAN interfaces, create and configure VLANs on the switch, and assign VLAN
membership to Layer 2 interfaces. For more information, see
Chapter 11, “Configuring VLANs.”
• Configure Layer 3 interfaces.
• Enable IPv4 routing on the switch.
• Assign IPv4 addresses to the Layer 3 interfaces.
• Enable selected routing protocols on the switch.
• Configure routing protocol parameters (optional).
Configuring IP Addressing
A required task for configuring IP routing is to assign IP addresses to Layer 3 network interfaces to
enable the interfaces and allow communication with the hosts on those interfaces that use IP. These
sections describe how to configure various IP addressing features. Assigning IP addresses to the
interface is required; the other procedures are optional.
